Abstract:
A vacuum cleaner having a vacuum cleaner body, a suction fan and motor operatively associated with the vacuum cleaner body, and a wheel. The wheel has a wheel body having an axis of rotation, a tread surface, and a cushion layer radially interposed between the wheel body and the tread surface. The cushion layer includes a resilient shell having a plurality of resilient cells therein. The shell and the plurality of cells have one or more gasses in them, and are dimensioned to damp vibrations and impacts between the tread surface and a floor surface that the tread surface contacts as the wheel rotates about the axis of rotation.
